Yeah, there's a lot of good ones out there, but I stick mainly to a few stalwarts. Don't want to blow up my laptop yet, but the temptation is hard to resist not adding that 'final touch' that slows your PC to the speed of molasses ... I need a new PC, where's Santa in the summer?

This might be a dumb question... but what is a global blender and how do you add it? o.o I have figured out how to add specific shaders to different parts...but how do you add more than one? Like one on say, the lamp, and also one over the entire scene?

Global blender - that's a term I coined so may not be universally known - but basically its an MME effect that affects the entire scene. Common ones are SSAO and Diffusion. They usually load as an accessory model. You can have multiple blenders loaded at the same time.

Gobal shaders/blenders effect the entire scene, the individual models themselves can have separate effects applied to them and still benefit from the effects of the global effects.
